Hello. I'm a new member and this is my first post here. I came across this site many times over the past week in my search to identify a handful of parts I received.
There seems to be a great deal of knowledge being shared and maybe another member could identify these four parts. I have attached four pics, one for each part.
Any help would be appreciated. Thank you in advance...

Welcome to the forum @deewoof !

The first board (20221111_223043.jpg) is a DTC 5290-CZ 16-bit ISA MFM hard drive controller. It supports 2 drives.
The second board (20221111_223111.jpg) is a Compaq 32-bit custom memory expansion board for a DeskPro. It appears to have 2MB of RAM onboard.
The third board (2022111_223143.jpg) is an 8-bit ISA Keithley Metrabyte data capture/collection card.

The fourth board (20221111_223215.jpg) is a Heathkit 8-bit ISA EGA video card, that allows the connection of either a digital EGA or analog VGA monitor

Hope this helps!
